The Wireless Waffle blog has produced an interesting article about the reports drawn up by the regulatory administrations monitoring unauthorised use of the shortwave spectrum.
He has been through the report and picked out pirates whose activities have been noted by the monitoring stations. But the report does not make clear what happens once the station is noted . . . very few shortwave pirates tend to be raided, unless there is a specific complaint about QRM.
It is also worth noting there are also many international stations, such as Cairo, North Korea and China, who also transmit outside the international broadcast bands. Nothing seems to happen to them.
As the Wireless Waffler notes, these reports raise a lot of questions . . . but not many answers. He also has a link to the actual ITU monitoring reports themselves which feature a lot more than just the shortwave pirates.
